A genuine alternative to the sewing of synthetic textiles, fabric welding enables seams to be made without stitching or assembly marks, and is characterized by its strength, watertightness and high quality.<\/p>

However, textile welding is not limited to synthetic fibers, as natural fiber fabrics can also be welded in the same way, after a prior coating operation to give them the characteristics required for welding.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Based on the assembly of fabrics made of synthetic fibers, or on the assembly of fabrics composed of both natural and synthetic fibers, textile welding can be carried out using either ultrasonic or high-frequency technology.<\/p>

Ultrasonic welding is a rapid joining technique that involves vibrating the fabric strips to be joined at a frequency of between 20 and 70 kHz. The resulting heat causes the thermoplastic fibers to melt, thus joining the fabric elements to be welded. Ultrasonically-coated textile welding makes it possible to join fabric parts made from a mixture of synthetic and natural fibers, with a very clean finish. <\/span><\/p>

High-frequency welding of textiles (RF or HF welding) is based on the generation of a high-frequency electromagnetic field that causes a dielectric effect on the materials. The agitation of molecules in both synthetic fibers and thermoplastic coatings on natural fibers ensures that fabrics are welded together, resulting in very strong assemblies with a high level of finish. <\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Coating is a technique used to modify the technical characteristics of a textile or fabric, whether made from natural fibers (cotton, linen, wool, etc.), artificial fibers (viscose, lyocell, etc.) or synthetic fibers (polyamide, polyester, acrylic, etc.). Whereas coated textiles are single-layered and undergo a treatment to modify their surface into a uniform coating compound, coated fabrics are composed of at least two layers of material: the fabric layer and the polymer coating layer. Textile substrates most representative of this technique include PVC-coated fabrics<\/strong>, PU<\/strong> (polyurethane) coated fabrics<\/strong>, PVC-coated textiles<\/strong>, etc. <\/p>\n

Visit textile polyurethane coating<\/span> is characterized by its watertightness and low stainability. It protects against chemicals and does not conduct electricity. In general, all woven textile substrates with a high proportion of synthetic fibers can be coated for welding: <\/p>\n
